Spa Installation Spa & Hot Tub Installation My relationship with Oregon Hot Tub has greatly expanded the opportunities I have had to build some very unique structures. We do everything from pouring concrete support slabs to gazebos, privacy screens, modifying existing decks, and of course, building new ones. There is a bit of an art to properly placing, and orienting a new spa. There are important factors such as the best view, spa equipment door access, cover lifter limitations, and overall ease of use. We can reinforce a new or existing deck to place a spa on top of it, or install it adjacent or sunk into a deck area. In general, the easier they are to use, the more they are used.
